This fixes a memory leak in the CPU profiler: https://bugs.chromium.org/p/v8/issues/detail?id=6623

This affects master, 9.x and 8.x. master should pick this up through a regular V8 update (if the merge gets approved). This PR is for 9.x. This should cherry-pick to 8.x easily except for the version bump, which will need to be migrated to v8-version.h.

Original commit message:

[cpu-profiler] Clear code entries when no observers are present.

Performed manual testing as well by making 20 CPU profile recordings of
loading http://meduza.io page. Without the patch the page renderer memory size
grows beyond 300MB. With the patch it remains below 200MB.

Failing test was fixed in #17383
fips failure is unrelated (fix for flake also landed)

@MylesBorins I'm getting an error with this on v8.x-staging.

I'm going to back it out for now, but if I'm doing something wrong let me know and we can re-land.

@gibfahn I can reproduce the issue. I am investigating.

This is the V8 6.1 specific backport for Node 8.x. Original commit message: [cpu-profiler] Clear code entries when no observers are present. Performed manual testing as well by making 20 CPU profile recordings of loading http://meduza.io page. Without the patch the page renderer memory size grows beyond 300MB. With the patch it remains below 200MB.
